Bukkit

After a restart:

2012-02-14 19:47:28 [SEVERE] Error occurred while enabling RadioBeacon v1.1 (Is it up to date?): Antenna loading failed, no world with name: world_islands
        at me.exphc.RadioBeacon.Antenna.<init>(RadioBeacon.java:155)
        at me.exphc.RadioBeacon.AntennaConf.loadAntennas(RadioBeacon.java:1087)
        at me.exphc.RadioBeacon.AntennaConf.load(RadioBeacon.java:1050)
        at me.exphc.RadioBeacon.RadioBeacon.onEnable(RadioBeacon.java:1243)

Of course, world_islands exists, people made Antennas there just fine while server was running.

All I'm doing to get the world:

            world = Bukkit.getWorld((String)d.get("W"));
            if (world == null) {
                throw new RuntimeException("Antenna loading failed, no world with name: "+ d.get("W"));
            }

Why could getWorld() be failing?

Released 1.1.2, now ignores antennas from unrecognized worlds instead of throwing an exception. But this doesn't necessary solve this problem here.. not sure why the new worlds wouldn't be detected.
